audio2tape converts audio files to ZX Spectrum tape images.
- -t type
- causes type to be used as the level detection
trigger. There are two triggers implemented; the simple trigger
just uses a threshold value to convert to a one or zero on output, and the
schmitt trigger implements a Schmitt trigger which outputs a less
noisy signal, but requires a stronger signal to noise ratio than the
simple trigger. The default trigger is “schmitt”.
- causes the display of a frequency graph showing the sound
levels present in the audio file. This can be useful when selecting good
- causes any ROM blocks that are recognised to use idealised
timing figures rather than the exact ones found in the audio file.
- causes the tape file that is produced to keep any audio
data from the original audio file that isn't recognised. This will allow
unsupported loading schemes, encryption tones etc. to be preserved in the
file that is produced.
- -z level
- causes level to be used as the zero point in the
supplied audio file, it allows adjustment for a DC offset in the audio
file. The default level is 127 from a range of 0–255.
- -c level
- causes level to be used as the Schmitt trigger noise
threshold, this reduces the sensitivity to noise in the provided file. The
default level is 8 from a range of 0–127.
- -h, --help
- give brief usage help, listing available options.
- -V, --version
- output version information.
- specifies the audio file to be converted. This file can be
in any of the sound formats supported by libaudiofile.
- specifies the output tape file. The format will be
determined by the file extension and can be in any of the formats
libspectrum(3) supports for output.
